Differences are demonstrable in proximal and distal lesions to the crypts, and depression of activity of enzymes of membrane digestion in a homogenate of small intestine is demonstrable in the presence of the radiation-induced enteric syndrome in rats and mice (900 to 1400 R). There is the most intensive depletion in the rat jejunum, whereas the distal segment of the ileum is affected to an appreciably lesser extent. The crypts in the middle segment of the small intestine are more resistant to radiation in mice.
